Title:
TEMPERATURE MEASURING CIRCUIT AND MEASURING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2019/071844
Kind Code:
A1
Abstract:
A temperature measuring circuit and a measuring method thereof relating to the field of electronic circuits. The temperature measuring circuit comprises a control unit (U1), wherein the control unit (U1) comprises a first current output interface (IEXC1), a second current output interface (IEXC2), a first input/output interface (AIN3), a second input/output interface (AIN2), and a third input/output interface (AIN7). Further, the first current output interface (IEXC1) and the first input/output interface (AIN3) of the control unit (U1) are respectively electrically connected to a first interface (CN1-1) of a temperature sensor (CN1); the second current output interface (IEXC2) and the second input/output interface (AIN2) of the control unit (U1) are respectively electrically connected to a second interface (CN1-2) of the temperature sensor (CN1); the third input/output interface (AIN7) of the control unit (U1) is electrically connected to a third interface (CN1-2) of the temperature sensor (CN1). Thus, a temperature measuring circuit compatible with a temperature sensor (CN1) having a two-wire or three-wire system is implemented.
